摘要
由于溶洞的特殊性,传统测量仪器已经不能满足当前对溶洞探测的要求。三维激光扫描技术采用非接触式高速激光测量方式,能在复杂的现场和空间对被测物体进行快速扫描测量,从而获得点云数据。文中介绍激光扫描的工作原理及三维激光扫描的工作流程,并给出采用Riegl LMS_Z420i三维激光扫描仪对吉首至茶洞高速公路吉首岸索塔基坑下的溶洞进行探测的实例。
Because of cave s specific characteristics,traditional measuring instruments,nowadays,failed to perform well in detecting a cave.Adopting non-contact high-speed laser measurement,3-dimension laser scanning technology can quickly scan and measure objects to obtain point cloud data under a circumstance with complex scene and space.This essay has introduced relative theories of laser scanning as well as processes of 3-D laser scanning.Also,it provides an instance—detecting caves of foundation pit under cable t...
